53 Engine
Detroit Diesel Corporation (DDC) has supplied over 80,000 6V-53 engines throughout the world for powering the M113 family of vehicles, from the initial diesel rating of 212 horsepower, to the RISE engine at 275 hp.
Now a higher power density engine is available at 400 horsepower providing over one horsepower per cubic inch displacement for future M113 modernization.
The Affordable Solution
As vehicle capacity and payload demands increase, the upgraded M113 platform provides an affordable solution for applications up to 40,000 pounds. Battlefield mobility characteristics will not be sacrificed as the 6V-53, 400 horsepower engine will allow heavier M113 derivative vehicles to meet or exceed the mobility of the Abrams and Bradley fighting vehicles.
Technology Insertion for 400 HP
DDC has initiated a development program to raise the 6V-53T to a new technology level. With the adaptation of the current DDEC III electronic system and intercooling, the 6V-53T aftercooled 350HP engine will be upgraded to 400HP.
This new level of horsepower of over 1.25 HP per cubic inch displacement will allow vehicles to achieve added weight while still meeting or exceeding the mobility and speed of other lead vehicles on the battlefield.
Detroit Diesel Electronic Controls (DDEC)
The major components of the system consist of the electronic control module (ECM), the electronic unit injectors (EUI) and the various system sensors. The purpose of the sensors is to provide information to the ECM regarding various engine performance characteristics. The information sent to the ECM is used to instantaneously regulate engine and vehicle performance.
Engine Protection System
Costly engine damage can be avoided with the engine protection features. The ECM will begin the protection process when it receives a signal from the oil or coolant temperature, oil pressure, coolant level sensor or two additional vehicle sensors advising it that an operating condition is out of specification. Each sensor can be programmed for shutdown, rampdown, or warning.
Glow Plugs
To improve cold weather startability, DDC developed a glow plug system which assures unassisted cold starting down to -25°F. The system consists of a controller, wiring harness and individual glow plugs for each engine cylinder. This system has consistently allowed us to achieve bare engine test cell cold starts at -25°F within four seconds of starter engagement.
Insulated Exhaust Components
Thermal wrapping of the external engine exhaust components can reduce radiated heat to the engine compartment, improving engine performance and increased durability/reliability. DDC has released new thermal wrapped exhaust components using an advanced technology CMD-1987 material. Testing has demonstrated an external wrap temperature reduction of 850°F from an exhaust gas temperature of 1100°F.
Charge Air Cooling System
Advanced technology, high efficiency cooling systems play an integral part in meeting the overall future combat vehicle requirements for fuel economy, engine efficiency and overall vehicle performance. In order to reduce the temperature of turbocharged intake air for optimized combustion, Detroit Diesel is utilizing aftercooling and intercooling.
